Angular2路由器和多个解析在一个路由中

在ui-router中,很容易在路由配置中定义多个解析,所以我们可以这样说:

export const APP_STATES: Ng2StateDeclaration[] = [
  {
    name: 'dashboard',
    url: '/dashboard', 
    component: DashboardComponent,
    resolve: [
      {
        token: 'playbookDurations',
        deps: [DashboardService],
        resolveFn: (svc: DashboardService) => svc.getPlaybookDurations()
      },
      {
        token: 'playbookSuccesses',
        deps: [DashboardService],
        resolveFn: (svc: DashboardService) => svc.getPlaybookSuccesses()
      },
      {
        token: 'playbookRuns',
        deps: [DashboardService],
        resolveFn: (svc: DashboardService) => svc.getPlaybookRuns()
      },
      {
        token: 'activityLog',
        deps: [DashboardService],
        resolveFn: (svc: DashboardService) => svc.getActivityLog()
      }
    ]
  }
}];

import { Resolve, ActivatedRouteSnapshot, RouterStateSnapshot } from '@angular/router';
import { Injectable } from '@angular/core';
import { DashboardService } from '.';

@Injectable()
export class DashboardResolver implements Resolve {

  constructor(private dashboardService: DashboardService) { }

  resolve(route: ActivatedRouteSnapshot, state: RouterStateSnapshot) {
    return this.dashboardService.get();
  }

}

import { DashboardComponent } from './dashboard.component';
import { DashboardResolver } from './dashboard.resolver';

export const routes = [
  { 
    path: '', 
    children: [
      {
        path: '', 
        component: DashboardComponent,
        resolve: {
          data: DashboardResolver
        }
      }
    ]
  }
];

{
  path: '', 
  component: DashboardComponent,
  resolve: {
    foo: Resolver1
    bar: Resolver2,
    // more resolves here...
  }
}

@Component({ ... })
export class MyComponent {

  constructor(private route: ActivatedRoute) { }

  ngOnInit() {
    const foo = this.route.snapshot.data['foo'];
    const bar = this.route.snapshot.data['bar'];
  }

}
